Hey There SS,
A dude that worked for me had the same problem. His eye Doc had him put marks on a pair of glasses which represented his normal "field of view" while long linin'. Using those marks, the Doc super-glued "add-on" corrective lens segments to try out. Once he was comfortable with the field of view they custom ground a permanent set of glasses that he uses for flyin'. He claims no problems in lookin' at the gauges or the overhead panels and can still feel comfortable leanin' out all day.
So..., that's just one dude's solution - there's probably a lot more out there.
Good luck!
